I like the method Ignacio suggested but the project is actually a little more complicated...

I got a building in L-shape.
While the left side has 3 existing stories the right side has only 2.
Adding new (modern) stories with different heights than the existing ones results in different story heights of the two sides from the 3 level up which is a common problem in ArchiCAD.

A solution to this is, as I already found out, using .mod files and hotlinking them to a project file. That said I have two mod-files each containing one of the sides..

Hi Barry
This sounds quite interesting. Could you expand on this? What "filter" are you referring to? Don't the renovation filter limit you to three status'...?

Would this work if you had 3 house design options on the same site, modelled all in-situ, using three different renovation filters to control viability. Wouldn't they try to intersect with each other and create all sorts of issues?

So long as they are set to show only in a particular filter then they do not seem to interact with other elements set to show in other filters.
They do interact with anything set to 'show in all relevant filters' or other elements in their own filter.

So in theory you could have as many versions as you want.

Just be aware there is no way to show everything on screen all at once.

The other way we were taught of how to achieve multiple options in a single file was through the use of "spare" stories way up in space, then saving them as modules, and placing them in-situ. The modules get linked to a publisher set, so if a change is required, they are amended in their source in the spare stories, then you re-publish the module, go to the Hotlink Manager, click update etc.
